Loose-LEAF BINDER.

SpecificationY of Letters Patent.

Application iled July 16, 1915. Serial No. 40,166.

To all whom t may concern:

Be it known that we, CARL H. BissELL and FRANCIS WARE CLARY, citizens of the United States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Loose-.Leaf Binder, of which the following is a specification.

Our invention has for its object the production of a loose leaf binder, which is particularly simple in construction and highly eliicient and durable in use; and it consists in the novel features of construction here@ inafter set forth and claimed.

In describing this invention, reference is like characters deslgnate corresponding parts in all the views.

Figure 1 is a front elevation of our loose leaf binder, the usual cover being removed and leaves being shown as held by the binder. y

Fig. 2 is a section on line A-A, Fig. 1, the covers for the back being also shown.

Fig. 3 is a section on line B--B, Fig. 1.

Fig. 4 is a horizontal section on line- C-C, Fig. 2.

Fig. 5is a detail view of the upper back section and parts associated therewith.

This loose leaf binder comprises, generally, a back, posts carried by the back, a clamping member movable lengthwise of the posts, and means for operating the clamping member. The back is here shown as composed of two telescoping sections, and the posts each include telescoping sections carried respectively by the back sections.V

1 and 2 designate the upper and lower sections of the back, each section being shown as formed with end walls 3 or 4, a rear wall 5 or 6, and a top or a bottom wall 7 or 8, the sections bein open attheir front sides in order that -t e leaves A may be inserted therein.

The sections 1 and 2 telescope with each other and are held from separating in various positions determined by the number of leaves bound therein, by suitable means here shown as latches 9 provided on the end walls of one section and coacting with shoulders 10 provided on the end Walls of the other section, the latches having a series of teeth 11 for coacting with the shoulders 10.

low and telescoping with an arc-shaped shoulders 10 project inwardly from the end walls 3 of the upper outer back section 1 through lengthwise slots 13 in the end walls 4 of the inner section 1. The latches 9 are arranged to move across the slots 13 in positron to engage the shoulders 10, and are proylded with outturned lips or finger engag: ing pieces 14, which normally lap the edges of the end walls 3, 4 of the back sections 1, 2.

15 and 16 designate the sections of each post, these sections being carried respectively by the top and the back sections, the section 15 being holwithin theV hollow section 16, and both the sections 15, 16 having alined lengthwise slots, 17, 18. The sections 15, 16 are formed respectively with feet 19, 20 which are secured to the inner faces of the top and bottomwalls 7, 8 of the back sections.

21 designates the clamping member movable along each post, this clamping member having a tongue 22 extending through the alined slots 17 18 into the interiors of the post sections 15, 16, the clamping member having its body extending on the outside of bottom walls 7, 8 of Patented May 29, 1917.

the post in order to press against the leaves A and hold them from separation. As seen in Fig. 4, the clamping member 21 is formed passage 23 through which the post extends, this arc-shaped passage forming the tongue 22.

The means for operating each clamping member 21 comprises a screw 24 extending lengthwise of each post in the sections 15, 16 thereof and threading into the tongue 22 of the clamping member, the screw having its head 25 exposed on the outside of the back, as on the upper side of the top wall 7. The screw is held from endwise movement Aby an annular flange 26 thereon near its head located in the annular recess formed in the foot 19 of the post section 17. The back sections may be provided with suitable covers 27.

In operation, the back sections 1, 2 can be separated by operating the latches 9, this separating movement also separatin the post sections and removing the clamping A members with the upper post sections 15.

the interior of the post, and a body on' thickness of the leaves by reason of the series of the shoulders 1l of the latches 9.

What we claim is:

1. A loose leaf binder comprising a back, a post carried by the back, a clamping member movable lengthwise of the post, and means for moving the clamping member, said means extending lengthwise of the post and being accessible at one end of the post, substantially as and for the purpose specifled.

2. `A loose leaf binder comprising a back, a hollow post supported by the back, a clamping member movable lengthwise of the post, and means for operating the clamping member, said means extending lengthwise of the post within-the same and being exposed at one end of the post, substantially as and for thepurpose set forth.

3. A loose leaf binder comprising a back, a hollow post supported by the back, a

lclamping member movable lengthwise of the post, and a screw extending lengthwise of the post and threading into the clamping member and having a head exposed at one end of the post, the screw being held from axial movement, substantially as and for the purpose described.

. Y 4. A loose leaf binder comprising a back, a post supported by the back, said post being hollowand formed with a lengthwise slot, a clamping member having a tongue eX- tending through the slot and slidable along 'the outside of the post, and means extending lengthwise of the post for operating the clamping member, substantially as and for iso4 the purpose specified.

5. A loose leaf binder comprisingn a back, a post supported by the back, said post being hollow and formed with a lengthwise slot, a clamping member having a tongue extending through the slot and slidable along the interior of the post, and a body on the outside of the post, and means extending lengthwise of the post for operating the clamping member, said means comprising a screw threading into the tongue, the screw having a head exposed at one end of the post` substantially as and for the purpose set forth.

6. A `loose leaf binder comprising a back, a post carried by the back and including telescoping sections, a clamping member movable lengthwise of the sections, and means for operating the clamping member extending lengthwise of the post and having a head accessible at one end of the post, substantially as and for the purpose described.

wise slots, a clamping member having a tongue extending through `the slots and a body portion surrounding the post, and a screw extending lengthwise of the post and threading into the tongue and having a head exposed at'one end of the post, substantially as and for the purpose set-forth.

9. A loose leaf binder comprising a back, a hollow post formed with a lengthwise slot supported by the back, a clamping member formed with an arc-shape passage through which the post extends, the clamping member having a tongue extending through the 'slot and into the interior of the post, and a screw extending axially into the post and threadin into said tongue, substantially as and for t e purpose described.

10. A loose leaf binder comprising a back including upper and lower sections, one telescoping within the other, a post supported by the back. and including telescoping sections carried respectively by the sections of the back, a clamping member 4movable lengthwise ef the post, and means extending lengthwise of the post` and coacting with the 'clamping member to operate the same, said means having a head exposed on the outside of the back at one end of the post, substantially` as and for the purpose set forth.
